Memory and Future: Remembering Dave Waltz

Remembering Dave Waltz (1943-2012)

Remembering the past and imagining the future in the elderly.

Recent research has demonstrated commonalities between remembering past events and imagining future events. Behavioral studies have revealed that remembering the past and imagining the future depend on shared cognitive processes, whereas neuropsychological and neuroimaging studies have shown that many of the same brain regions are involved in both remembering the past and imagining the future. ...

Remembering the past and imagining the future: Identifying and enhancing the contribution of episodic memory.

Recent studies have shown that imagining or simulating future events relies on many of the same cognitive and neural processes as remembering past events. According to the constructive episodic simulation hypothesis (Schacter and Addis, 2007), such overlap indicates that both remembered past and imagined future events rely heavily on episodic memory: future simulations are built on retrieved de...

Eye movements disrupt episodic future thinking.

Remembering the past and imagining the future both rely on complex mental imagery. We considered the possibility that constructing a future scene might tap a component of mental imagery that is not as critical for remembering past scenes. Whereas visual imagery plays an important role in remembering the past, we predicted that spatial imagery plays a crucial role in imagining the future. For th...

tion after completing his dissertation in 1972 at the Massachusetts Institute of Technology Artificial Intelligence Laboratory (MIT AI Lab). That dissertation created the field of constraint propagation by showing that constraints and a rich but simple descriptive system were sufficient to recover threedimensional information from a two-dimensional projection. Besides an education, Dave picked ...
